Since you are using the 442 for alot of write operations, you will
use up the battery. If you are doing so at home, why not use the
adaptor.
We have used ours continuously throughout a day with it plugged in.
The 442 has worked longer than 9 hours for us. If you keep it in
a cool place, like a CamelBak, it lasts much longer.

well when transferring files your using the Hard Drive more than if you playing a song. The battery life is weird on the 442 so when recording and transferring files you should always consider using the charger...
With Lithium Ion batteries i don't think they have a memory so it wouldn't be necessary to empty and then recharge it.
